28 Claims.

This invention relates to lasting machines, and more particularly to machines for lastin the sides of the foreparts of shoes beyond their toe portions, including especially their ball portions. An immediate object of the invention is to provide improvements in a machine such as machine, but it should be understood that it is not thus limited in its applicability.

The machine shown in the above-mentioned application is particularly adapted for lasting the sides of the foreparts of shoes of that kind in which the margin of the upper in those locations is lasted over an insole in parallel relation to the bottom of the last and is fastened to the insole by cement. For that purpose the machine is provided with wipers carried by arms which are moved about axes extending heightwise of the shoe, the wipers comprising thin steel plates which are resiliently flexible in directions heightwise of the shoe for better conformity to the contour of the bottom of the shoe in response to increased pressure of the shoe against them when they are over the shoe bottom. Associated with the wipers are retarders which in response to the operative inward movements of the wiper carrying arms are moved outwardly over the insole toward the wipers into positions to clamp the margin of the upper against the edges of the wipers, the retarders preventing the margin of the upper from adhering prematurely to the insole and insuring also that the margin of the insole is properly positioned on the bottom of the last. The retarders cooperate with the wipers to pull the margin of the upper inwardly over the extreme edge of the insole, whereupon they are moved heightwise of the shoe out of the paths of the wipers by the movements of the wiper- I carrying arms and are then moved outwardly over the wipers as the latter continue their inward wiping movements.

An object of this invention is to improve results in the operation of such a machine on portions of a shoe where the edge of the shoe bottom curves inward heelwardly of the ball line, especially when such curvature is pronounced and when the previous lasting of the shank portion ofthe shoe ha terminated at a substantial distance from the ball line. To this and other ends, the machine herein shown is provided with additional wipers movable inwardly be above-mentioned wipers (which for purposes of designation may be termed the main wipers), the additional wipers wiping the margin of the upper over the insole inlocations where the edge of the shoe bottom curves inward heelwardly or the ball line and having components of movement toward the toe end of the shoe along the wiping faces of the main wipers. The additional wipers thus wipe the margin of 'the upper inwardly in directions substantially perpendicular to the inwardly curved portions of the edge of the insole, which is desirable for the best results in the lasting operation. Furtherto insure the proper lasting of the portions of the upper on which the machine operates, provision is -a-f-- forded for the additional wipers to begin their lasting operations on the upper earlier than the main wipers, the construction shown being also such that they terminate their inward wiping movements after the beginning but prior to' the termination of the wiping action of the main wipers on the upper. The additional wipers, in the construction shown, comprise thin steel plates which are flexible like the main wipers. and as further herein illustrated they are carried by arms which are swung about axes extending heightwise of the shoe and are operated by the arms which carry the main wipers.

The invention further provides additional retarders arranged to cooperate with the additional wipers, these additional retarders, in the construction shown, being moved outwardly over the insole in difierent directions than the retarders associated with the main wipers, with component of movement away from the toe end of the shoe, in view of the directions of movement of the additional wipers. For this purpose they are carried by arms mounted to swing about axes extending heightwise of the shoe in the appropriate locations, these arms being operated by the same means whereby outward movements are imparted to the retarders associated with the main wipers. A illustrated, the additional retarders are forced heightwise oi the shoe away from the insole by pressure of the margin of the upper against them, whereupon they are moved farther outwardly over the additional wipers in the course of the wiping operation,

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed tween the shoe and the wiping faces of the 55 out in the claims.

Like the machine shown in the. previously men-- tioned' application, the; machine herein shown is provided with. a column 2 terminating at its: up.- per end. ina horizontal: shelf. 4 on which aresecured the. lower endsof' two: vertical frame plates 6' spaced apart 'wid't'hwise; of the: machine and integral at their. upper ends. with: a horizontal. top plate 3-. Pivotally' mounted? sulostantia-l'lymid-- way between its opposite; ends; ona bifurcated member It fast on: this top: plate is. aforwardly and. rearwa-rdlyextending lever [2. provided at its front end with aholiddowrr member: M; (Fig. 2') arranged. toengage. the. bottom of: the: iorepart of the shoe to.' d'eterminelthe position oi the. shoe heightwise' and with; respect; to tipping-s movements about. axes: extending lengthwise and laterally thereof. The-position. ofi' the-shcealengthwise is determined; as hereinafter described, the end gageiprovide'cl for that purpose in the earlier construction. being omitted.- Its positionwidthwise is determine'd by a-pair of side gages It (Fig. 4) arranged to contact with the opposite sides of its ball portion, these gages being secured to upwardly extending arms of bell-crank levers It. The belt-crank levers are pivotall'y'supported on an arm 20 (Fig; l=') extending forwardly from a plate 22' which is part of a vertical cylindex 24 mounted on the shelf 4 between the frame plates 6 for a purpose hereinafter described, and theyare adjustable by means of a screw 26 to vary the distance between the two side gages 86, as more fully disclosed in the previously mentioned application.

After the shoe has been presented by the operator bottom upward under the h'olddown M and between the side gages t6, it isclamped against the holddowna shoe rest 28 which engages the topof its forepart'. The shoe rest is supported on an arm 3!! fast on a rockshaft 372 mountedon the frame plates 5; and also fast on one end of this rockshaft is another arm 34 connected to a treadle 35 by depression of which the operator moves the shoe rest upwardly into engagement with the'shoe. The connections between the treadlh and the-arm (M include a rod 38 connected by a turnbuckle All" to another rod 42 slidingly movable a block 44 which is pivotally mounted on the rear end of the arm 3 4', and further include a spring it'mountecl between a collar 48 resting on the block 44 and a collar 50 .held by a nut 52 on the rod 42. Accordingly the spring 46 is yieldable in response to further depression of the treadle 36 after the shoe rest 28 has been moved into position to clamp and hold the shoe.

For wiping the margin of the upper inwardly over the insole at the opposite sides of the ball portion of the shoe the machine is provided as heretofore with a pair of comparatively thin steel wipers 54 resiliently flexible in directions heightwise of the shoe and each secured by a pair of bolts 56 (Fig. 2) to a forwardly extending arm 58 of abell-crank lever 60 pivotally mounted" on a stud' 62 on the top plate 8 to swing about an axis extending heightwise of the shoe. The two. bell-crank. levers $0 have other arms 64 extending widthwise of the shoe in crossed relation to each other and connected by links 66 to upwardly extending arms, 88 of other bell-crank levers Ill. mounted on a rod 12. to. swing about an axis extending, widthwise of the shoe, this rod being, supported. on an arm T4. extending rear- Wardly from the previously mentioned. plate 22.. Forwardly extending. arms 16 of the bell-crank levers 1.53 are. connected by linksv 18 to a rod which extends. through vertical slots 82. in the sides of. the previously mentioned cylinder 2.4 andv through a. piston 84 in the cylinder- In. response toupwardmovement of this piston,.therefore, wiper-operating movements are imparted through. thebell-crank levers Til tothe bell-crank levers. 651., the. wiper-carrying arms 58 of thelatter being swung inwardly toward each. other.

Such upward movement of the piston; 84 is efiected by operating fluid, which may be com.- pressed'. admitted to the. lower. end. of the cylinder 2%.. For. this purpose thecylinder is connected by a. conduit. 86 to. valve mechanism 83 whichcontrols the admission and exhaust of. air to. and. from. the cylinder... The-valve. mechanism comprises a tube. 99: clamped between. two blocks 92 and 94:. fast on an inclined arm 95 extending rearwardly from the shelf 4. One. endof. the. tube 9.0. i's-.in.communicaticn through a passageway in thebl'ockv 92 with the. conduit 8.5, and the other end. of the tube. is. in communication with a conduit. 9.8. leading. from a suitable source. of. com.- pressed. air supply... Midway of its. length the tube. has a partition. Hill extending. across. it, and extending. through the walls of the. tube. at the. opposite. sides of this partition, respectively, are ports Hi2. and I'M. Movable. along. the tube isv a. sleeve valve H16 provided. with an annular chamber I 88 which,.when the valve is in one position, provides. communication between the ports m2 and I04 and thus admits compressed air to the cylinder 2'4. When the valve is. in the position shown in Fig. 1 the ports I02 are open. to the atmosphere and the piston. 84 is at. the lower end of the cylinder, in which position it is maintained by springs llil connected to the arms .16. Movement of the valve into position to admit compressed. air to the cylinder is effected by further movement of the treadle 36 after the shoe rest 28 has been moved into shoe-clamping position. For this purpose an arm H2 is pivotally mounted at H4 on the supporting arm 96' and is provided with a pin H6 extending into a groove in the valve Hit. The valve ismaintained normally in its initial position, determined by its engagement with the block. 84 as shown in Fig. 1, by a spring I I8 connected to a pin I20 onthe arm H2. This pin extends through a slot I22 in an inclined link I24 pivotally connected at its'lower end to a collar I26 fast on the treadle-operated rod 38. When this rod is moved downwardly, therefore, downward movement is imparted to the link I24, but by reason of the slot I22 in the link no movement is imparted to the valve-operating arm IIZ until after the shoe rest 28 has been moved into clamping position. Further movement of the treadle thereafter against the resistance of the spring 46 serves to move the valve I86 into position to admit compressed air to the cylinder 2s and thus tocause the wipers 54 to be operated. When the treadle is released by the operator after the operation of the machine on a shoe, it is raised by a spring I28 connected to a collar I38 fast on the rod 38, and by the action of this spring return movement is imparted to the link I24. This permits the valve I86 to be moved by the spring II8 into position to open the ports I82 to the atmosphere and thus to permit exhaust of the air from the cylinder 24, the wipers being returned to their initial positions by the action. of the springs H8. Return movement of the treadle is limited by engagement of a screw i32 (Fig. 2) threaded in an arm I34 fast on one end of the shaft 32 with a lug I36 on one of the frame plates 6.

When a shoe is pressed upwardly against the holddown I 4 by the shoe rest 28, movement of the lever I2 by the pressure of the shoe on the holddown is prevented by an arm I38 mounted to swing about the rod 72 and provided with a roll I46 which underlies the rear end of the lever. A spring I42 connected to the arm holds it normally in an upright position determined by engagement of the roll I453 with a lug M4 on the lever. When the wipers 54 have substantially or nearly completed their inward wiping movements the arm I38 is swung rearwardly to release the lever I2 and thus to permit the shoe to be pressed more forcibly up against the wipers by the shoe rest 728 under control of the spring 46, thus insuring that all portions of the margin of the upper wiped inwardly by the wipers will be pressed firmly down on the insole. To effect such swinging movement of the arm I38 the upwardly extending arms 68 of the bell-crank levers I8 carry a yoke member I46 provided with a screw I48 arranged to engage the arm I38, the screw being adjustable to determine the time with respect to the operative movements of the wipers when their pressure on the upper is increased. The initial position of the lever I2 is determined by a stop I56 on the top plate 8, against which the front arm of the lever is held by a light spring I52.

The bolts 56 which secure the flexible wipers 54 to the arms 58 are located substantial distances widthwise of the shoe from the shoeengaging portions of the wipers, and accordingly these portions of the wipers are left free throughout their lengths to be flexed or bent by the increased upward pressure of the shoe against them when the lever I2 is released as above described. This permits the wipers to conform satisfactorily to the more or less convex lengthwise and lateral curvatures of the bottom of the ball portion of the shoe and thus to apply adequate pressure to all portions of the margin of the upper on which they act. The arms 58, however, carry screws 854 and I56 arranged to engage the top faces of the wipers at their front and rear ends, respectively, to limit the bending of the shoe-engaging portions of the wipers as a whole, andthe support which the screws thus afford for the frontand rear ends of the wipers after they engage them contributes to such further bendengaging the top of the arm I68.

ing of the portions of the wipers between the screws as to conform properly to the lengthwise curvature of the bottom of the ball portion of the shoe. The wiper-carrying arms 58 are braced against upward deflection by the pressure of the shoe on the wipers by means of blocks I58 fast on the top plate 6 and under portions of which the arms are moved in operating the wipers, these blocks having shoulders I60 which by engagement with the arms limit the operative movements of the wipers. The wipers are maintained in a heated condition, as is preferable in lasting with cement, by electrical heating units I62 mounted in blocks I64 secured to the lower faces of the wipers. The studs 62 about which the wipers are swung are at such a distance apart that the wipers have small components of movement lengthwise of the shoe toward its toe end as they are moved inwardly widthwise of the shoe.

Arranged to cooperate with the wipers 54 to control the margin of the upper as it is wiped inwardly over the insole are retarders I66 which press or clamp the margin of the upper in upstanding position against the edges of the wipers prior to and at the beginning of the wiping operation and also serve to press the margin of the insole down on the bottom of the last. These retarders extend substantial distances lengthwise of the shoe and are curved which positions the arms are swung outwardly to carry the retarders toward the side edges of the insole and toward the wipers by means hereinafter described. Each retarder has an offset upwardly extending cylindrical portion I'I I 6) mounted in a socket in the arm I68 and engaged by a spring I16 which tends to move the retarder downwardly, the limit of its downward movement being determined by a collar I'IB fast on a stem I86 extending upwardly from the cylindrical portion N4, the collar normally Initially the retarders I66 extend downwardly short distances beyond the holddown I4, and they are moved upwardly against the resistance of the springs I76 by pressure of the shoe thereon when the shoe is pressed upwardly against the holddown by the shoe rest 28.

Insurance is thus afforded that the retarders will press the insole down On the bottom of the last when they are moved outwardly toward the wipers. Connected to pins on the collars I18 are springs I82 which initially hold the retarders in definite positions with respect to turning movements about the axes of the stems I66 but permit them to turn and adjust themselves'to the wipers when the upper is pressed against them by the wipers.

For swinging the arms I68 outwardly to carry the retarders toward the side edges of the insole there are provided other arms I84 (Figs. 1 and 2) mounted on studs 86 on the plate 8 to swing widthwise of the shoe and connected to the arms 'l68 by links I88. Also mounted to swing about the studs I86 are plates plates is held at all times in predetermined I66. Eaclrof these adiusted relation. to the. arm [84: associated there.- with: by means including an' adjustmg screw: I92, as fully disclosed. in the previously mentioned application; Each plate is. provided with a pro- J'ection I94 arranged to beengaged by a. finger I96 formed. on or secured to. the adjacent wiper-carrying arm 58. When the two arms 58, therefore, are swung inwardly tooperate. the wipers the fingers I96 have a. cam-like. action. on the plates; 5% to swing these plates. and the arms I84 as units in outward directions, thus swinging the retarder-c'arrying arms I68v outwardly against the resistance ofthe spring I12. In this manner the retarders I66 are: moved. out.- wardly over the insole toward the wipers as the wipers are being movedv inwardly toward the side edges of the insole, the retarders serving to spread. fromv over the insole any portion. of. the margin of the upper which may extend inward.-

ly over it. At the time when. the outwardly moving retarders and. the inwardly moving. wipers arrive in positions to clamp the upstanding margin of the upper between them. the retarders preferably are so located that their upper-engaging faces are positioned slightly farther outward than the side edges of the insole, so as to detach from the edges: of the. insole any portion of the upper which may have ad'- hered prematurely thereto. In. order that the retarders may thus be properly positioned relatively to the side edges of the insole in operating on shoes of different widths, the plates I96 are adjustable about the studs I86 relatively to the arms I84 by the screws IG2. In this manner the time in the movements of the arms 58 when their fingers I96 begin to swing the arms I84 and the retarders outwardly may be varied to vary the distances the retarders are thus moved before the upper is first clamped against them by the wipers.

Each of the links I88 is mounted to swing in directions heightwise of the shoe about a stud I93 on the end of the arm I8d associated therewith, the main portion of the link being also so mounted as to permit it to swing in directions lengthwise of the shoe about a pin 2&0 relatively to the portion thereof which is mounted on the stud I98. The inner end. portion of the link (Fig. 6) is so shaped as to' extend downwardly and then inwardly under the cylindrical portion I'M of the retarder I66, the inner end of the link being provided with a slot 292 through which a headed stud 294 extends downwardly from the cylindrical portion I1 5. A spring 266 connected to the link I88 and to the arm I68 tends to swing the arm outward relatively to the link and holds it normally in a relation to the link determined by engagement of the stud 204 with the link at the outer end of the slot 202. As the wipers continue their inward movements from the positions where they first clamp the upper against the retarders I66 they force the retarders inwardly against the resistance of the. springs 206, the studs 294 being moved inwardly along the slots 202. In this manner the wipers and the retarders cooperate to apply an inward pull to the margin of the upper over the extreme. edge of the insole. Shortly after the wipers begin to wipe the margin of the. upper inwardly, however, the retarders are lifted against the resist.-

ance of the springs I16 to withdraw them from the paths of the wipers. For this purpose the links I88 have adjustably supported thereon rolls 268 (Fig. 6.) which are engaged by the wipercarrying arms 58 to swing the links upwardly amass":

about: the studs IE8? and thereby to: lift. the. re;- tardersa. the retarders have thus been lifted they are moved outwardly over the wipersa by: contraction of the springs 266 andby the continued swinging movements of the arms I84. At the beginning of such outward movements: of the-retarders over the wipers they bend the margin' ofv the upper outwardly and thus increase: the effectiveness; ofv the wipers in wiping the upper tightly and smoothly over the insole.

As thus far described, the machine herein shown may be assumed to be constructed substantially as. disclosed in the previously mentioned application- For purposes of this invention there are provided additional wipers. 2H! for wiping the margin of the upper inwardly over the insole in locations where the. edge of theshoe bottom curves inward heelwardly of the ball line; These wipers comprise thin steel plates resiliently flexible like the wipers 54 and arranged to be moved inwardly over the shoe bottom. between the shoe and the wipers 54 in con.- tactwith the wiping faces of the latter. The wipers: 2I'IJ: are fast on forwardly extending arms 2I2' oflevers 2M mounted to swing about the axes of vertical pins 256' to which they are secured and which are rotatable in hearings in brackets ZIB on the frame plates 6. Swinging. movements are imparted to the levers 2I4 to operate the wipers 2w by the movements of the arms 53 which carry the wipers 54. For this purpose the arms 58 are connected to the forwardly extending arms N2 of the lovers 2 by links 226 pivotally connected at their inner ends to' the arms 53 and slidingly movable in blocks 222 pivoted on the arms 2I2. Between these blocks and nuts 224 on the outer ends of the links are springs 226 which are yieldable to permit further inward swinging movements of the arms 58 after movements of the levers 2M have been stopped as hereinafter described. Nuts 228' on the links serve by engagement with the blocks 222 to impart return movements to the levers 214-. As the wipers ZIU are thus operated they have substantial components of movement lengthwise of the shoe toward its toe end along the wiping faces of the wipers 54 by reason ofthe locations of the pins EIG, which are farther apart widthwise of the shoe than the studs 62' about which the arms 58 are swung, and by reason of the shape of the arms 2I2 which are curved inwardly toward each other widthwise of the shoe. The wipers 2), therefore, wipe the margin of the upper inwardly over the inwardly curved portions of the edge of the insole extending heelwardly of the ball line in directions substantially perpendicular to these portions of the edge of the insole, as is desirable for satisfactory results in the lasting operation. The wipers 2H] are heated by their contact with the heated. wipers 5'3, and they may bend with the wipers 54 to conform better to the contour of the bottom of the shoe when the pressure of the shoe on all the wipers is increased in the manner hereinbefore described. The arrangement of the links 226 relatively to the arms 53 and the arms 25 2 is such that the wipers 2) are moved inward more rapidly than the wipers 5.4 and begin to act on the upper earlier than the wipers 54, as is desirable in operating on portions of the upper extending heelwardly of the ball line. To prevent the wipers 2&0 from being moved. too far inwardly over the shoe bottom and too far toward the toe. end of the shoe relatively to the wipers 54, the machine is provided with means for stopping their inward movements prior to the completion of the inward movements ofthe wipers 54. For this purpose each of the brackets 2I6 has thereon an outwardly extending rod 236 on which is threaded a nut 262 arranged to be engaged by the bifurcated rear end of a rearwardly extending arm 236 of the lever 2%. It will be understood that by adjustment of the nuts 262 the limits of the inward movements of the wipers 2H! may be varied each independently of the other.

Arranged to cooperate with the additional wipers 2I6 are additional retarders 236 which clamp the margin of the upper against the edges-of these wipers, these retarders also pressing corresponding portions of the margin oi the insole down on the bottom of the last. The retarders 236 are carried by arms 266 mounted to swing about the previously mentioned studs I86 about which also swing the arms I84 and the plates I66 whereby outward movements are imparted to the retarders I66 associated with the wipers 54. The retarders 236 are provided with stems 240 extending upwardly through the arms 23B and having fast on their upper ends collars 242 for limiting downward movements of the retarders. Springs 264 connected to these collars hold the retarders 266 normally in predetermined positions with respect to turning movements about the axes of the stems 240 but permit them to turn in such manner as to adjust themselves to the edges of the wipers against which they clamp the margin of the upper. The arms 238 are swung to carry the retarders 236 outwardly over the insole into positions to clamp the vupper against the wipers 2III by the outward swinging movements of the plates I90 and the arms I84. For this purpose these plates have pins 266 extending upwardly into slots in the arms 238 and engaged by spring 268 in the arms. When, therefore, the outward swinging movements are imparted to the arms I84 corresponding movements also are imparted to the arms 233 through the springs M8. By reason of the locationsof the studs I66, the retarders 236 are swung outwardly with components of movement lengthwise of the shoe away from its toe end, as is appropriate in view of the directions of movement. of the wipers 2I6. To return the arms 238 to :theirv initial positions the pins 246 act'on screws 256 which-are threaded in the arms and are engaged by the-pins, the arms being adjustable about :the studs I66 by means of these screws. Whenthe retarders 236 first clamp the margin "of the upper against the wipers 2I6 the retarders are ;positioned substantially at the edge of thednsole. The retarders, however, are provided with, in: clined upper-engaging faces (Fig. 5). and. they are movable upwardly against the resistance of springs 252 in the arms 238 in response tojthe pressure of the upper against these facesas the wipers begin to wipe the upper inwardly over the insole. In this manner the retarders are forced heightwise of the shoe out of they paths of the wipers, whereupon they are moved farther out-1 wardly over the wipers by continued outward movements of the arms 236, bending the margin of the upper outwardly over the edges of;,.thewipers to render the wipers more effective in wip-: ing the upper tightly inward'over'the' insole; The outward swinging movements of the arms- 238 are limited by stop screws 254 threaded in the brackets 2H3 and arrangedto be engaged bylugs 256 on the arms,'in order to avoid'interference between the retarders 236 and other parts of. the

machine. It will be understood that when the movements of the arms 238 are thus stopped the springs 248 are yieldable to permit continued outward movements of the arms I84 which control the retarders I66.

In the use of the machine the operator presents a shoe between the side gages I6 with the bottom of its forepart against the retarders I66 and 236. When the shoe is thus presented the retarders 266 are conveniently utilized to indicate the proper position of the shoe lengthwise, the shoe, however, being so positioned by the operator that these retarders are located at some distances inwardly from the portions of the edge of the insole over which the margin of the upper is to be wiped by the corresponding wipers 2I0. After thus presenting the shoe the operator by depression of the treadle 36 swings the shoe rest 28 upwardly and thereby forces the shoe upwardly against the holddown I4, lifting the several retarders a short distance against the resistance of their controlling springs I16 and 252. Further depression of the treadle then serves to compress the spring 46 and to move the valve I06 into position to admit compressed air to the cylinder 24. By the action of the piston 84 the wipercarrying arms 58 are then operated to impart inward movements to the wipers 54, and through the linkconnections 226 between these arms and the arms 2I2 the latter also are operated to impart inward movements to the additional wipers 2H]. As hereinbefore explained, and as illustrated in Fig.- 3, these wipers arrive in positions to begin to wipe the margin of the upper over the inwardly curved portions of the edge of the insole extending heelwardly of the ball line be.- fore the wipers 54 arrive in positions to begin their wiping action on the upper, and they terminate their inward wiping movements by reason of engagement of the arms 234 with the stop nuts 232 after the beginning but prior to the completion of the wiping action of the wipers 54 on the upper, the springs 226 yielding to permit the latter wipers to complete their movements. As the several Wipersare thus moved inwardly the fingers I96 on the Wiper-carrying arms 56 have a camlike action on the projections I94 of the plates I to impart outward swinging movements to these plates and the arms I84, these arms actin through the links I88 to move the retarders I66 outwardly over the insole toward the wipers 54. At the same time outward swinging movements are imparted to the arms 238 to carry the retarders 236 outwardly over the insole toward the wipers 2H], these arms being operated by the plates I66 through the pins 246 and the springs 248. It will .be understood that the several retarders serve to spread from over the insole any portion of the margin of the upper which may extend inwardly over it and thereafter to clamp or press the margin of the upper against the edges of the corresponding wipers toprevent it from adhering prematurely to the insole and to render the wipers more effective to last the upper tightly and smoothly over the last and the insole. Additionally they serve to insure that the'margin of the insole i properly positioned on the bottom of the last when the upper is wiped overitby the wipers. The retarders 236 arrive in positions to clamp the upper against the wipers 2H1. substantially at the edge of the insole before the retarders I66 arrive in a corresponding relation to the wipers 54, and as the' wipers 2H] continue their inward movements the retarders 236 are forced upwardly by the pressure of the margin'of the upper on their inclined faces, as illustrated in Fig. 5. 'When these retarders have been forced upwardly far enough to "clear the wipers they are carried outwardly over them by the arms 238, bending the margin of the upper outwardly over the edgesof the wipers 'as they begin their outward movementsover them. Such-outward movements of the retarders 236 are limited by'engagement of the lugs 256 on the arms 2-38 with the stop screws 2-54 -'(F-i'g. 4) Shortl-y after the wipers 2-H! begin to wipe the 'marginofthe upper over the insole the retarders L66 "arrive in positions to clamp the margin of the upper against the edges of the inwardly moving wipers -54substantially at the edge of the insole. Thereafter the retarder-s 166 cooperate with the wipers '54 to apply an inward pull to the margin of the upper "over the extreme edge of the insole GEig. 6), whereupon they are lifted clear of the paths of the wipers by the action-of the arms "58-on the rolls 288 and are then moved 'outwardlyoverthe wipers by continued outward swinging *movements of the arms F84, asmoreiull-y disclosedin the previously mentioned application. 'As they begin to move outwardly "over the wipers they bend the margin of th'e'upper-over the e'dgesof the wipers, as illustrated in Fig. '7. Near the end of the inward wiping movements of the wipers 54 the holddown 'supportih'g lever 4-2 is released by the arm 138, thus permitting the spring 46 by itsac'tionon-theshhe rest 28' to force the shoe more firmly up against the several wiper-s which may bend to "conform better to the contour of the shoe bottom. The operator preferably holds the treadle depressed long enough to-cause the heated-Wipers 'to continue "for a few seconds th'eir pressure on the overwiped margin 0f the upper, thus allowing more time for the cement to set while the upper is pi-essed smoothiy on 'the'in'sole. The operator then "releases the treadle, whereupon'the various =pa1 ts*are returned to their starting positions by -'reason' o'fthe release-of the-compressed air from the cylin'der 24.
